Methods of Balance: The Different Types of Hormone Therapy
Hormone therapy works by either lowering the amount of hormones in your body or blocking them from reaching cancer cells. This guide explains the different ways this is achieved through tablets or injections.
Please remember that every patient is unique; your consultant and medical team are the best judges of the most suitable treatment plan for your specific case.
Not all cancers are the same. Some, particularly certain types of breast and prostate cancers, are "hormone-sensitive." This means they use the body’s natural hormones—like oestrogen or testosterone—as fuel to grow and spread.
The goal of your treatment is to cut off this fuel supply. Depending on your age, your general health, and the specific nature of the cancer, your doctor will choose one of two main strategies: blocking the receptors or stopping production.
The shield method
The most common form of hormone therapy is a daily tablet. This method is often used for many years to keep the cancer from returning.
Think of the cancer cell as a locked room and the hormone as the key. For the cancer to grow, the hormone key must enter the lock. These tablets work by sitting inside the lock so the key cannot get in.
Because the "lock" is already occupied by the medicine, the hormone has nowhere to go and the cancer cell cannot receive the signal to grow. This is a very effective way of keeping the disease in check while you go about your normal daily life.
Lowering hormone production
Sometimes, blocking the "lock" isn't enough, and the doctors want to reduce the total amount of "keys" (hormones) your body produces in the first place. This is often done using a different type of medication that tells your brain or your glands to slow down production.
Aromatase inhibitors: These are tablets usually given to women after menopause. They stop the body from making small amounts of oestrogen in the body's fat and muscle tissues.
LHRH agonists: These are usually given as an injection (sometimes called a "depot") once a month or once every three months. These injections send a signal to the body to stop the main production of hormones at the source.
Forms of delivery
In an Indian household, we are often more comfortable with tablets, but injections play a vital role in hormone therapy.
The daily routine: If you are prescribed tablets, the most important factor is taking them at the same time every day. This keeps the "fuel level" in your body consistently low.
The clinical visit: If you are prescribed injections, these are usually done by a nurse at your local clinic or hospital. These injections are designed to release the medicine slowly over several weeks, so you don't have to worry about it every day.
Combining strategies
Occasionally, a consultant might suggest using both a tablet and an injection. This is not a cause for alarm; it simply means they are attacking the "fuel supply" from two different angles. They are both stopping the production of the hormone and blocking any remaining hormones from reaching the cancer cells. This "double-lock" strategy provides the highest level of protection for certain types of cases.
Conclusion
Whether you are taking a daily pill or visiting the clinic for a three-monthly injection, the goal of hormone therapy remains the same: restoring balance and starving the cancer of its fuel. By understanding whether your medicine is a "blocker" or a "producer-stopper," you can feel more in control of your journey.
